- Decora-Style Single-Gang Plate Integrates Cleanly Into Commercial Wall Installations
- 100W Input Capacity Supports High-Demand Distributed Speaker Zone Loads
- Wide Operating Temperature Range Suits Mechanical Rooms And Unconditioned Spaces
The TOA AT-100EMG-AM is a 100W, 70-volt wall attenuator designed for installed audio environments where local volume control must coexist with centralized paging or emergency notification. System integrators specifying distributed speaker systems in corporate facilities, schools, healthcare buildings, and houses of worship will find it well-suited where code or operational policy requires that emergency or paging signals reach listeners regardless of where a local attenuator is set.
The unit provides 13 attenuation steps in 3dB increments, giving building occupants smooth, predictable volume adjustment without the impedance-matching problems common to simpler resistive controls. The integrated 24 VDC relay at 15mA automatically bypasses the attenuation circuit when an override signal is applied, restoring full signal level at the local speaker without requiring staff intervention or manual reset. This makes it a practical fit for mass notification and paging systems where manual override reliance is a liability.
The single-gang Decora-style white plate mounts in standard electrical boxes, keeping the installation clean and consistent with other wall devices in commercial interiors. At 100W capacity and designed around 14-gauge cable runs, the AT-100EMG-AM handles demanding zone loads that lighter attenuators in the same form factor cannot match.
